Introduction
Organic chemistry is a chemistry sub discipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.

Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Alicyclic compounds | A chemical compound with an open-chain molecular structure rather than a ring-shaped structure; for example, the alkane series. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Alcohols | Alcohols (R-OH) take the suffix "-ol" with an infix numerical bonding position: CH3CH2CH2OH is propan-1-ol. The suffixes -diol, -triol, -tetraol, etc., are used for multiple -OH groups: Ethylene glycol CH2OHCH2OH is ethane-1, 2-diol. |
Real life uses :
Study the nature of chemicals.

Practical examples around us
| Examples | Explainations |
|---|---|
| ketones | In general ketones (R-CO-R) take the suffix "-one" with an infix position number: CH3CH2CH2COCH3 is pentan-2-one. If a higher precedence suffix is in use, the prefix "oxo-" is used: CH3CH2CH2COCH2CHO is 3-oxohexanal. |
What you learn in Theory:
When a ring of three or more carbon atoms resembling aliphatic compounds are contained in homocyclic or carbocyclic compounds, they are called alicyclic compounds. The saturated alicyclic hydrocarbons have the general formula CnH2n.
What you learn in Practice:
An open chain system of carbon atoms may be either straight chains (non-branched) or branched. The open chain compounds are also called aliphatic compounds.
